Oh dear, you think every comment on HN is a direct reply to the title? No, comments are arranged in a tree structure. For example, the comment you're reading right now is a reply to your previous comment, not to the title. It's not just HN that structures its comments this way--it's a very popular schema, so this bit of knowledge should be really helpful for you on your Internet adventures. Godspeed!
The comments were related to each other, and indirectly to the title. This discussion has descended into obtuseness, and I find obtuseness to be boring, so I’ll dip out.
